摘要： PROBLEM TO BE SOLVED: To provide a structure capable of stabilizing the ratios of intensities at every main wavelength component contained in output beams at every product to a light emitting device constituted so as to conduct a cascade excitation by a GaN light emitting element and a phosphor.
SOLUTION: The light emitting device is constituted while having the GaN light emitting elements emitting an original excitation light L, a primary phosphor member 1, and a secondary phosphor member 2. The primary phosphor member 1 contains primary phosphors 10 being excited by the original excitation light and emitting a primary fluorescence L1. The secondary phosphor member 2 contains secondary phosphors 20 being excited by the primary fluorescence L1 and emitting a secondary fluorescence L2. The primary phosphor member 1 and the secondary phosphor member 2 are arranged as mutually other members, so that the primary phosphors 10 and the secondary phosphors 20 independently exist while being divided into mutually different space regions without being mutually mixed.
